Brake light wiring

zxabx

Hey,
I just bought a 2000 XR650R. I can't get the brake light wired in correctly. I bought:
- Baja Designs Dual Sport LED Dropdown Taillight
- K&S Dual Sport Hydrualic Brake Light Switch
from xrsonly.com. I have a green and a brown wire coming from the bike. On the tail light I have a red, black, and blue wire. From the brake switch I have a red wire and a black wire. What the heck goes where???
